Prospective Screening In Multiple Endocrine Neoplasia Type 1, Britt Skogseid, Kjell Oberg
Prospective Screening In Multiple Endocrine Neoplasia Type 1, Britt Skogseid, Kjell Oberg
Henry Ford Hospital Medical Journal
To assess the age of clinically detectable onset of multiple endocrine neoplasia type 1 (MEN 1), 88 members of four families were invited to participate in a ten-year biochemical screening program. Evidence for clinically detectable MEN 1 was found in adolescence. Pancreatic endocrine dysfunction constituted the presenting lesion in a majority of these individuals. The age at diagnosis of pancreatic endocrine tumors averaged 25 years and was lowered by almost two decades by prospective investigation. Furthermore, the penetrance of the pancreatic endocrine and parathyroid lesions equaled the penetrance found in autopsy studies. The use of a standardized meal stimulation test …

Prad1 (Cyclin D1): A Parathyroid Neoplasia Gene On 11q13, Andrew Arnold, Toru Motokura, Theodora Bloom, Carol Rosenberg, Allen Bale, Henry Kronenberg, Joan Ruderman, Milton Brown, Hyung Goo Kim
Henry Ford Hospital Medical Journal
Hyperparathyroidism is a central component of multiple endocrine neoplasia type 1 (MEN 1), and both sporadic and familial forms of parathyroid disease may share certain pathogenetic features. We recently identified a gene that is clonally rearranged with the PTH locus in a subset of sporadic parathyroid adenomas. This candidate oncogene, PRAD1 (previously D11S287), appears to contribute to parathyroid tumorigenesis in a fashion analogous to activation of C-MYC or BCL-2 by rearrangement with tissue-specific enhancers of the immunoglobulin genes in B-lymphoid neoplasia. The PRAD1 gene maps to 11q13 and has been linked to the BCL-1 breakpoint locus, although not to the …
Surgical Treatment Of The Endocrine Pancreas And Zollinger-Ellison Syndrome In The Men 1 Syndrome, Norman W. Thompson
Surgical Treatment Of The Endocrine Pancreas And Zollinger-Ellison Syndrome In The Men 1 Syndrome, Norman W. Thompson
Henry Ford Hospital Medical Journal
Islet cell neoplasia is a frequent occurrence in multiple endocrine neoplasia type 1 (MEN 1). Sixteen of 27 patients with MEN 1 developed functioning endocrine pancreatic tumor syndromes. Eleven of the 16 developed Zollinger-Ellison syndrome and each was evaluated by a combination of computed tomography and hepatic angiography to exclude hepatic metastasis and percutaneous transhepatic catheterization to localize the tumor. Seven of the 11 patients were found to have duodenal gastrinomas with multiple duodenal tumors in three patients. Four of the 11 patients had only pancreatic gastrinomas. In addition to the gastrinomas, other types of islet tumors in the pancreatic …

The hereditary conditions of primary cutaneous lichen amyloidosis and multiple endocrine neoplasia type 2 (MEN 2) are rare clinical entities. The initial reports of two families in which the two conditions coincided have led to the identification of at least eight additional families with this clinical syndrome. In this report we describe the clinical features in five of these eight families. The salient feature in these five families is the presence of unilateral (46%) or bilateral (64%) pruritic and lichenoid skin lesions located over the upper portion of the back. Family members describe these skin lesions as intermittently intensely pruritic …

Henry Ford Hospital Medical Journal
Familial multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant disorder characterized by the combined occurrence of tumors of the parathyroid glands, the endocrine pancreas, and the pituitary gland. MEN 1 tumors have previously been shown to be associated with the loss of alleles on chromosome 11, and deletion mapping studies together with family linkage studies have localized the MEN 1 gene to 11q13. A detailed genetic map around the MEN 1 locus is required to facilitate further characterization and cloning of the gene (MEN1). We have characterized a panel of seven rodent-human somatic cell hybrids which contain …

Practical Guidelines For Dna-Based Testing In Multiple Endocrine Neoplasia Type 1, Catharina Larsson, Magnus Nordenskjold, Britt Skogseid, Kjell Oberg
Henry Ford Hospital Medical Journal
Multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant predisposition to neoplastic lesions of the parathyroid glands, the neuroendocrine pancreas, and the anterior pituitary gland. The predisposing genetic defect was localized to the long arm of chromosome 11 by genetic linkage analysis in three affected families. By analyzing six MEN 1 families with 14 DNA marker systems located close to the MEN 1 gene, we have developed a method to identify carriers of the MEN 1 predisposition. We describe practical aspects of such DNA-based diagnostic procedures.
Parathyroid Tumor Biology In Familial Multiple Endocrine Neoplasia Type 1: A Model For Cancer Development, Maria Luisa Brandi
Parathyroid Tumor Biology In Familial Multiple Endocrine Neoplasia Type 1: A Model For Cancer Development, Maria Luisa Brandi
Henry Ford Hospital Medical Journal
Familial multiple endocrine neoplasia type 1 (FMEN 1) is an autosomal dominant disorder characterized by tumors of the parathyroid glands, pancreatic islets, and anterior pituitary. Hyperplasia appears to be the typical histopathological lesion in FMEN 1 endocrine tumors. A circulating mitogen related to basic fibroblast growth factor was active on proliferation of clonal bovine and human parathyroid endothelial cells. Moreover, the FMEN 1 mitogen modulated differentiation of human parathyroid endothelial cell in vitro. All these facts suggested that an extrinsic factor was active on parathyroid endothelial cell growth and differentiation. The FMEN 1 gene maps to chromosome 11q13, and allelic …
Hyperparathyroidism With Normal Albumin-Corrected Total Calcium In Patients With Multiple Endocrine Neoplasia Type 1, J. J. Shepherd, Bin Tean Teh, V. Parameswaran, R. David
Hyperparathyroidism With Normal Albumin-Corrected Total Calcium In Patients With Multiple Endocrine Neoplasia Type 1, J. J. Shepherd, Bin Tean Teh, V. Parameswaran, R. David
Henry Ford Hospital Medical Journal
In the largest reported family of patients with multiple endocrine neoplasia type 1 (MEN 1), hyperparathyroidism was expressed at first screening in 33 patients by elevation of ionized calcium (IC) (30 cases) or parathyroid hormone (three cases) without elevation of albumin-corrected total calcium (ACTC). Three of these 33 patients have shown a progressive rise in IC and later an elevation of ACTC. However, the age distribution suggests that in others the level of IC may remain stable at a minimally elevated level throughout life with ACTC remaining normal except for transient rises at the times of intercurrent illness or surgical …
Isolation Of Yac Clones From The Pericentromeric Region Of Chromosome 10 And Development Of New Genetic Markers Linked To The Multiple Endocrine Neoplasia Type 2a Gene, Terry C. Lairmore, James R. Howe, Shenshen Dou, Rosalie Veile, Jennifer A. Korte-Sarfaty, Samuel A. Wells Jr., Helen Donis-Keller

Henry Ford Hospital Medical Journal
Genetic linkage mapping and contig assembly using yeast artificial chromosome (YAC) technology form the basis of our strategy to clone and define the genomic structure of the pericentromeric region of chromosome 10 containing the multiple endocrine neoplasia type 2A gene. Thus far YAC walks have been initiated from five chromosome 10 pericentromeric loci including RBP3, D10S94, RET, D10Z1, and FNRB. Long range pulsed-field gel electrophoresis maps are constructed from the YACs isolated to define clone overlaps and to identify putative CpG islands. Bidirectional YAC walks are continued by rescreening the YAC library with sequence-tagged site assays developed from endclones. Several …

Henry Ford Hospital Medical Journal
We studied the expression of the ret proto-oncogene (proto-ret) in human medullary thyroid carcinomas (MTCs) and pheochromocytomas of multiple endocrine neoplasia type 2A (MEN 2A) by Northern blot analysis. Expression of the normal-sized transcripts was detected in all 12 MTCs and in 6 of 8 pheochromocytomas. In situ localization of proto-ret mRNA revealed that the signal was confined to the cytoplasm of MTC cells. By Southern blot analysis neither amplification nor gross genetic changes of proto-ret were found in the tumors. Although no transcripts were detected in the normal portion of the thyroid from one MEN 2A patient,faint signals were …

Nine chromosome 10 DNA markers (FNRB, D10S34, D10Z1, MEN203, D10S94, RBP3, D10S15, MBP [48.11], D10S22) were typed in two large Canadian pedigrees with multiple endocrine neoplasia type 2A (MEN 2A). These markers and the gene for MEN 2A (MEN2A) are believed to be in one linkage group spanning approximately 15 cM (male). MEN203 and D10S94 were informative and tightly linked to MEN2A with no recombinants observed in 26 meiotic events. D10S15 (MCK2), widely used in DNA genotyping predictions, demonstrated two recombinants in these two families. The use of multiple flanking markers increases both the likelihood of informativeness and the accuracy …

Henry Ford Hospital Medical Journal
Seven members with multiple endocrine neoplasia type 2B from a 15-member family have been followed for 18 years. All affected had the neuroma phenotype in a distribution compatible with autosomal dominant inheritance. The phenotype features have allowed 100% initial and continuing prediction of affected versus nonaffected status in as early as 1.5 years. Among the affected: immunoreactive plasma calcitonin (iCT) concentration was high in 100%; thyroid palpation was false-negative in 71%; and thyroid scintiscan was false-negative in 83%. All had total thyroidectomy, plus lymphadenectomy in three, for bilateral medullary thyroid carcinoma (MTC) or C-cell hyperplasia (in the youngest). None has …

Unusual Features Of Multiple Endocrine Neoplasia, Andrea Frilling, Heinz Becker, Hans-Dietrich Roeher
Henry Ford Hospital Medical Journal
In addition to the common presentations of the multiple endocrine neoplasia (MEN) syndromes, unusual organ involvement as rare manifestations of a single disease may occur. Among our patients we have identified four cases in which unusual features of MEN were present. In the first patient, bilateral adrenal cortical adenoma, parathyroid adenoma, multiple pancreatic tumors, and follicular thyroid carcinoma were observed. The second patient suffered from thymic carcinoid, parathyroid hyperplasia, gastrinoma, and pituitary adenoma. Additionally, one family was discovered in which medullary thyroid carcinoma (MTC), Hirschsprung's disease, and pheochromocytoma occurred and another family had MTC and ovarian cancer. Based on these …

Henry Ford Hospital Medical Journal
The frequency and significance of cervicomediastinal lymph node metastases have been investigated in 82 medullary thyroid carcinoma (MTC) patients retrospectively comparing two surgical techniques of lymph node dissection: selective lymphadenectomy (n = 63) versus compartment-oriented microdissection (n = 35). No positive correlation was observed between primary tumor size and the number of lymph node metastases. Inpatients with lymph node metastases proven histologically, 42% showed only cervical involvement (35% unilateral—type A, 7% bilateral—type B, and 22% cervicomediastinal lymph node involvement (15% cervico-unilateral and mediastinal—type C, 7% cervicobilateral and mediastinal—type D). Biochemical cure was 83% in node-negative patients but only 21% in …

To investigate the role of primary and/or secondary modified radical neck dissection (MRND) in patients with medullary thyroid carcinoma (MTC), follow-up data on 43 patients operated on between 1972 and 1983 were analyzed retrospectively; patients included 16 with sporadic MTC (group 1) and 27 with multiple endocrine neoplasia type 2 (group 2). Primary surgical therapy consisted of (near-) total thyroidectomy and limited lymph node dissection: one patient in group 1 and two in group 2 underwent primary MRND. Positive nodes were found in nine patients of group 1 and in 12 of group 2. Calcitonin (CT) was raised postoperatively in …

Pheochromocytoma: A Frequent Indicator For Men 2, Claude Calmettes, Myriam Rosenberg-Gourgin, Jean Caron, Nicole Feingold
Henry Ford Hospital Medical Journal
Pheochromocytoma is a frequent indicator of multiple endocrine neoplasia type 2A (MEN 2A); in the 35 French MEN 2A families in which a pheochromocytoma occurred first in some affected members, 30% of the patients had a pheochromocytoma as the first manifestation constituting 45% of all patients with pheochromocytomas. The finding of a pheochromocytoma is a strong indication for a search for medullary thyroid carcinoma and for initiating family screening.

Early diagnosis and surgical treatment of medullary thyroid carcinoma (MTC) in children is essential to decrease the likelihood of metastatic spread. From 1981 to 1991, eight children under 18 years of age (five girls and three boys) with MTC were seen and seven underwent total thyroidectomy. Followup ranged from 14 months to 10 years after surgery. Four of the seven presented with a neck mass and elevated basal levels of calcitonin (CT). After surgery, three had recurrent disease. In the other three, the diagnosis was made after several years of screening (normal basal values of CT but increased CT levels …

Somatostatin Acts Via A Pertussis Toxin-Sensitive Mechanism On Calcitonin Secretion In C-Cells, Angela Zink, Hans Scherubl, Friedhelm Raue, Reinhard Ziegler
Henry Ford Hospital Medical Journal
The effect of the somatostatin analog octreotide on cAMP-mediated calcitonin (CT) secretion and cAMP accumulation in C-cells was investigated. Glucagon stimulated cAMP accumulation and CT secretion with a maximal effect at a concentration of 10-6 M. The cAMP antagonist RpcAMPs blocked the glucagon-induced CT secretion down to control levels. Therefore, no other second messengers seem to be involved in glucagon-stimulated CT secretion. Octreotide in increasing doses (10-9 to 10-6 M) inhibited cAMP accumulation and CT secretion with a maximal effect at a concentration of 10-7 (40% and 29% of control values, respectively). Pretreatment of the cells …

Role Of Insulin-Like Growth Factor-I In The Autocrine Regulation Of Cell Growth In Tt Human Medullary Thyroid Carcinoma Cells, Kuo-Pao P. Yang, Naguib A. Samaan, Yi-Fan Liang, Socorro G. Castillo
Henry Ford Hospital Medical Journal
Since the TT human medullary thyroid carcinoma cell line required fewer exogenous growth factors (serum), we investigated whether this line has an autocrine mechanism by examining the effects of antibodies directed toward insulin-like growth factor I (IGF-I) and its receptor on TT cell growth in serum-free conditions. Treating cells with anti-IGF-I antibody for four days reduced the cell number by more than 50% compared with a nonimmune IgG control. Furthermore, a monoclonal antibody to the IGF-I receptor suppressed DNA synthesis when determined by a [3H]thymidine incorporation assay. Exogenous IGF-I (20 ng/mL) stimulated [3H]thymidine incorporation in serum-free …

Henry Ford Hospital Medical Journal
Neuroendocrine features and cytogenetic abnormalities of one continuous cell line (MTC-SK) and two long-term cultures (GER, STAH) derived from three sporadic cases of human medullary thyroid carcinomas (MTCs) were studied. Specific neuroendocrine markers (NSE, chromogranins, calcitonin, calcitonin gene-related peptide) were identified by electron microscopy and immunocytochemistry. In situ hybridochemistry and Northern blot analysis confirmed endocrine activity. Cytogenetic studies of the cell line MTC-SK revealed three consistent marker chromosomes, t(3;10), 11p+, and 22p+. Cells of long-term cultures GER and STAH exhibited a consistent translocation t(2;18), a trisomy 7, and two consistent marker chromosomes der3 and 5p+, respectively. Recently, we have isolated …

Extracellular Ca2+ Sensing In C-Cells And Parathyroid Cells, Hans Scherubl, Maria Luisa Brandi, Jurgen Hescheler
Henry Ford Hospital Medical Journal
An essential function of C-cells and parathyroid cells is to monitor the extracellular Ca2+ concentration. The Ca2+-dependent secretion of calcitonin (CT) and parathyroid hormone is known to be mediated by corresponding changes in the intracellular Ca2+ concentration. To address the question of whether Ca2+ influx through voltage-dependent Ca2+ channels couples the extracellular to the intracellular Ca2+, we applied the patch clamp technique to C-cells of the rMTC 44-2 cell line and to parathyroid cells of the PT-r cell line. The rMTC cells displayed dihydropyridine-sensitive, voltage-dependent, high-threshold Ca2+ channels which allowed ion …

Management Of Impotence After Treatment Of Carcinoma Of The Prostate, Dinesh J. Telang, Riad N. Farah
Henry Ford Hospital Medical Journal
Impotence commonly occurs as a result of treatment of carcinoma of the prostate. We review the etiology, evaluation, and treatment options available for these patients as well as our experience with fifty prostate cancer patients who underwent placement of penile prostheses. Several excellent alternatives are available for patients with impotence resulting from treatment of carcinoma of the prostate.
